Hubble Searching for Icy Worlds

NASA's Hubble Space Telescope is on the hunt for an icy world just beyond Pluto. The speedy New Horizons spacecraft will be visiting Pluto next year, and NASA scientists are looking for another pit stop for it to explore. Unfortunately, this icy object is tough to spot.
